Calling in to Sean Hannity’s radio show, Romney brings up Newt’s jewelry expenses.

Bay Stater: “As for him trying to reference a $10,000 rhetorical bet, the Speaker, as I recall, probably shouldn’t be talking about that given a $500,000 bill at Tiffany’s.”

Echoes CBS News interview in which Mitt says the Georgian is “not a middle class American.”

ALSO: Romney says he’s “in this for however long it takes to get the nomination.”
